Specification of Letters Patent. Patented Dec. 25, 191'?.

Application iled October 25, 1916- Serial No. 127,611,

To all whom t may concern:

Be it known that I, AUGUSTUS S. TRUE, a. citizen of the United States,residing at Arlington, in the county of Middlesex and State ofMassachusetts, haveinvented new and useful Improvementsin CombinationArbor-Presses, of which Vthe following is a specification. x v

The object of the present invention is to provide a base adapted to beused in .combination with a tool now in general use, .to provide .anarbor press. The tool with which such base is adapted to be combined iscommonly known as the .Crane puller, and is the basis of Letters Patent724,818, granted April 7, 1903. It is estimated that there are at thepresent time about fty thousand or sixty thousand Crane pullers in use,a large number of which are used in automobile repair shops andv ingeneral machine shops. The Crane puller has proved to be an extremelyuseful tool for some kinds of work, but it has not hitherto beengenerally useful for Vbench work.

The present invention provides a base adapted to be affixed to a workbench, .and may remain permanently on thebench, said base havingprovisions for having a Crane puller coupled to it so that the twodevices in combination with each other will provide an effective arborpress. The base is preferably made in such formA that a vehicle wheel,for example, may be placed upon it before the puller has been coupled toit, and has provisions adapted to enable the hook-shape links of thepuller to be moved laterally into hooked relation therewith v'after thelinks have been inserted linto diametrically opposite spaces between thespokes of the wheel. Vhen the base, puller, and a vehicle wheel areassembled as above stated, the arbor press is usable for forcingballraces or otherk elements into or out of the hub of the wheel. To belthus enabled to operate upon a wheel with a press of much smallerdimensions than the wheel is a great advantage, particularly as thepuller is readily detachable from-"its base and may be usedindependently of the base, while the base is usable for some purposesindependently of the pullen The invention therefore comprehendsprimarily the combination of a base with the well known puller aboveidentified; but inasmuch as the base is capable of manufac ture, use andsale, `independently of' the puller, the invention 'comprehends also v`such base per se asan article of manufacture, use and sale.

Of the accompanying drawings:

Figure'l represents a top plan view'of a base embodying the presentinvention, and includes the linksof a Crane puller, in section, incooperative relation thereto. VThe base is shown Vas being 'mounted upon'a bench. Y y Y j Fig. 2 represents a front elevation, partly insection, of the assemblage, includinga bench, the base mounted thereon,and. a Crane puller inv cooperative relation to the base. Y

The saine reference Ycharacters indicate the same parts Vwherever theyoccur. I will describe firstthe characteristic features of the wellknown Crane puller. This' `device comprises .a screw 10 and nut 11vfronrt-he screw 1() by shifting the pivotA members 11, 111 from onehole 13 to another. The free ends of the links have hooked portions 16.VAll the above-specified structural features of the puller are disclosedin the said Patent 724,818, excepting that in the present'instance the`holes 13 are substituted for the notched slots shown in the patent.This difference, however, isimmaterial so far as the present inventionis concerned.

The base hereinbefore referred to is indicated at 20. It is adaptedl tob e mounted upon and aiiixed to a bench such as that indicated at 21,and forthis purpose is provided with bolt-receiving holes 22. Vhenclamping bolts 23 `are inserted through thek cured Vto the bench, and ispreferably arranged in such relation tof'the edge-25 ofy vthe bench asto overhang such edge and leave a clear space below the overhangingportion for shafts, axles, or other objects upon which theA press may beused to operate.

For convenience of description the' everhanging portion of the base isindicated at 26. A work-receiving rec-ess 27 is formed in suchoverhangi'n'g portion, and a rotatable disk 28. is connected. to thebase by a pivot member 29 in such relation as to overhang the portion inwhich the recess: 27' is formed. The disk 28 is provided with aplurality or" notches 30` of various sizes each of which may be broughtinto register with recess 27 by turning the disk, and the latter servesas an anvil. yor support for the object to which pressure is to beapplied'.

The base is provided with sockets. or recesses 31 adapted to receive thelinks 15y of the pullen These sockets or recesses are preferably open atthe front of the base, as indicated. at 32, to enable the links 15 tomove laterally into them and out of them. When the links. are arrangedin the recesses 3l the. hook portions 16 are adapted to underlie andcoact with the edge portions 33 of the Vbase, to sustain whatever upwardstress is applied to thev links in consequence of downward stress of thescrew 10 upon an object lying upon the anvil 28.

In order to prevent the links l5 from bcing dislodged accidentally fromthe socket-s or recesses 31, the base is provided with retainingportions 3.4, 34, `behind which portions of the links 15 may be arrangedas shown by Fig.. l. Then, in order to prevent the links from beingdislodged from the retaining portions 34, the base is provided withsetscrews 35 adapted to be set up against the links. Vhen the setscrewsare set up tightly against the links, the weight of the puller issustained by the clamping action so produced, and the puller and basebecome, to all intents and purposes, a rigid unit. In order to permitdetaching the puller from the base the setscrews need be unscrewed onlyfar enough to enable the links 15 to pass around the retaining portions34 yand through the openings 32. The base and puller may therefore beassembled and taken apart very quickly.

When the puller is detached from the base the latter is useful for otherbench jobs, such as driving out rivets, tight-fitting bolts, or otherobjects.

Although I have explained how the puller and base may be used incombina-A tion with each other for forcing a ball-race into or out ofthe hub of a wheel, it is apparent that such combination is capable ofvery many other uses which it will not b necessary t0 state.

I claim:
